Shut-dump in ABAP WebDynpro

Question

Hi Guys,
I'm new to ABAP Webdynpro. I'm trying to display data in from table VBAP in webdynpro ALV and I get the following runtime error. Neither I'm able to debug the error (external break-point doesn't stop in my action event, may be it's dumping before that) nor able to get any clue waht exactly it means. Can somebody please help.
I get the error "Lower-Level Node with Name INPUT_VIEW.T_VBAP Does Not Exist".
I have 2 view in my application, INPUT_VIEW and OUTPUT_VIEW. My Input VIEW consists of node T_VBAK (wit 2 fields VBELN and ERDAT), and OUTPUT_VIEW with T_VBAP (with 4 fields VBELN, POSNR, MATNR, MATKL).
Thanks,
Satyaki.

Hi
You are right, VBELN and ERDAT are input fields and when user press the button following event triggers ONACTIONGET_DATA (button is associated to event GET_DATA). Inside this event, I have the following code. I was trying to debug this code if something wrong here with external debugger but systems dumps the error before it reaches here.
I'm copy pasting the code here... Can you please tell me - what is wrong with the code OR if you can guide me how to debug to check if select fails on VBAP.
